setup.py, make: avoid problems with outdated, existing hgext/__index__.py*

"make clean" already removed __index__.py[cdo], but not the __index__.py
(automatically generated by "python setup.py build_hgextindex").

"setup.py build_hgextindex" did not generate a new index if file
__index__.py[cdo] already existed, because if __index__.py was removed,
the compiled file containing the old information was imported and used.
Generate an empty file (with a new timestamp to generate a new .py[cdo])
instead and make mercurial.extensions ignore the unset docs attribute.

One of the problems was a failed test-help.t, to reproduce:

$ rm hgext/__index__.py*
$ echo 'docs = {"mq": "dummy"}' > hgext/__index__.py
$ make test-help.t

With this a "make clean" or "python setup.py build_hgextindex" helps.

Test "hg status" with combination of 'file pattern' and 'directory
pattern' for largefiles:

  $ hg status sub2/large6 sub2
  A sub2/large6
  A sub2/large7

Config settings (pattern **.dat, minsize 2 MB) are respected.

  $ echo testdata > test.dat
  $ dd bs=1k count=2k if=/dev/zero of=reallylarge > /dev/null 2> /dev/null
  $ hg add
  adding reallylarge as a largefile
  adding test.dat as a largefile

Test that minsize and --lfsize handle float values;
also tests that --lfsize overrides largefiles.minsize.
(0.250 MB = 256 kB = 262144 B)

  $ dd if=/dev/zero of=ratherlarge bs=1024 count=256 > /dev/null 2> /dev/null
  $ dd if=/dev/zero of=medium bs=1024 count=128 > /dev/null 2> /dev/null
  $ hg --config largefiles.minsize=.25 add
  adding ratherlarge as a largefile
  adding medium
  $ hg forget medium
  $ hg --config largefiles.minsize=.25 add --lfsize=.125
  adding medium as a largefile
  $ dd if=/dev/zero of=notlarge bs=1024 count=127 > /dev/null 2> /dev/null
  $ hg --config largefiles.minsize=.25 add --lfsize=.125
  adding notlarge
  $ hg forget notlarge

Test forget on largefiles.

Test addremove: verify that files that should be added as largefiles are added as
such and that already-existing largefiles are not added as normal files by
accident.

  $ rm normal3
  $ rm sub/large4
  $ echo "testing addremove with patterns" > testaddremove.dat
  $ echo "normaladdremove" > normaladdremove
  $ hg addremove

More rebase testing, but also test that the largefiles are downloaded from
'default-push' when no source is specified (issue3584). (The largefile from the
pulled revision is however not downloaded but found in the local cache.)
Largefiles are fetched for the new pulled revision, not for existing revisions,
rebased or not.

cloned (see test-subrepo-recursion.t):

(addremove will add *.dat as normal files now)
  $ hg forget large.dat
  $ hg forget large2.dat
  $ hg addremove -v
